Not much. Xinyi Wanjia is a trademark brand registered by Shenzhen Xinyi Fitness Equipment Co., Ltd. on January 10, 2014. The brand is increasing the difficulty to inspire its masses to love fitness.

At the same time, Xinyi Wanjia is favored by many consumers for its affordable price and excellent quality.
